Easy peasy.

$(function ()
{
    var $main = $('#main'),
        $1 = $('#1'),
        $2 = $('#2');
    
    $2.hide(); // hide div#2 when the page is loaded
    
    $main.click(function ()
    {
        $1.toggle();
        $2.toggle();
    });
});

OP Comment: "Is there anyway i can keep track of which div is visible?"

There certainly is; it depends on how you want to use it. You can manually maintain a flag:

$(function ()
{
    var $main = $('#main'),
        $1 = $('#1'),
        $2 = $('#2'),
        $visible;
    
    $2.hide(); // hide div#2 when the page is loaded
    $visible = $1;
    
    $main.click(function ()
    {
        $1.toggle();
        $2.toggle();
        $visible = ($visible === $1 ? $2 : $1);
    });
});

Or you can just write a function that figures it out for you:

$(function ()
{
    var $main = $('#main'),
        $1 = $('#1'),
        $2 = $('#2');
    
    $2.hide(); // hide div#2 when the page is loaded
    
    $main.click(function ()
    {
        $1.toggle();
        $2.toggle();
    });
    
    
    function whichIsVisible()
    {
        if (!$1.is(':hidden')) return $1;
        if (!$2.is(':hidden')) return $2;
    }
});

As jAndy points out, this function can be written in a more concise/terse form:

function whichIsVisible()
{
    return $1.add($2).filter(':visible');
}

However, it is semantically different from the first version. The first version returns one of:

• $1
• $2
• undefined

while jAndy’s version returns one of:

• $1
• $2
• $1.add($2), a two-element jQuery object
• $(), an empty jQuery object

So they’re not strictly equivalent.
